1Z0-1085-26 Practice Test 5 — 10 Questions

Question 1

You have a dynamic group named 'AppInstances' configured with the matching rule `instance.compartment.id = 'ocid1.compartment...'`. An instance is moved from this compartment into a different compartment. How quickly does OCI update the dynamic group membership for this instance?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Near-real-time (typically within a few minutes). Dynamic group membership evaluations happen dynamically and near-real-time as instances change states or compartments.

Answer

Only when the instance is stopped and restarted.

Answer

Dynamic group membership is static and never updates after initial creation.

Answer

Exactly every 24 hours during the daily IAM sync cycle.

Question 2

An application administrator is configuring a high-availability database cluster across three Fault Domains in a single Availability Domain. During a scheduled infrastructure maintenance event affecting Fault Domain 1, the administrator notices that one of the database nodes becomes unreachable. What is the expected behavior of OCI Fault Domains in this scenario?

Accepted Answer

Only instances in Fault Domain 1 are impacted by the maintenance, while instances in Fault Domains 2 and 3 continue to run normally without disruption.. Fault domains are isolated hardware and power groupings. Maintenance events or hardware failures impact only the specific Fault Domain being maintained, leaving other Fault Domains unaffected.

Answer

The database cluster automatically fails over its primary role to an instance in a different Availability Domain.

Answer

The entire Availability Domain is taken offline to synchronize the maintenance state across all Fault Domains.

Answer

Instances in Fault Domain 1 are automatically migrated to Fault Domain 2, causing a brief network partition.

Question 3

You are deploying a distributed database cluster that requires three nodes to be isolated from one another regarding underlying infrastructure failures. The chosen OCI region has only one Availability Domain. How should you provision the database instances?

Accepted Answer

Deploy each node in a separate Fault Domain (FD-1, FD-2, and FD-3) within the single Availability Domain.. When an OCI region has only one Availability Domain, you achieve high availability by placing instances across three distinct Fault Domains within that AD.

Answer

Deploy the nodes in the same Fault Domain and configure OCI Compute Auto-Scaling.

Answer

Deploy the nodes across three different OCI regions using asynchronous database links.

Answer

Deploy all three nodes in the same Fault Domain to maximize internal rack-level network performance.

Question 4

An architect is planning a multi-region disaster recovery deployment in OCI. Which THREE design considerations are essential for ensuring successful data synchronization and failover? (Choose three.)

Accepted Answer

Selecting secondary regions that offer the necessary service availability and capacity to run the production workload.. DR planning requires considering replication RPO, inter-region latency limits, and failover automation.

Answer

Routing all database replication logs through the public internet for maximum transparency.

Answer

Assuming that all OCI regions have identical network latency to all global internet service providers.

Question 5

An enterprise customer is reviewing their high availability architecture in OCI. They want to ensure their database and application tiers are protected against both localized hardware failures and major facility disruptions. Which THREE architectural practices should they follow? (Choose three.)

Accepted Answer

Distribute database nodes across distinct Fault Domains within an Availability Domain to protect against rack-level failures.. High availability across hardware and facility levels requires multi-AD deployment, multi-FD placement, and regular failover testing.

Answer

Rely solely on manual administrator intervention for all failover scenarios without automated health checks.

Answer

Consolidate all application and database nodes onto a single physical server in Availability Domain 1.

Question 6

Which TWO configuration steps are necessary when setting up private access from a VCN to OCI Object Storage using a Service Gateway? (Choose two.)

Accepted Answer

Add a route table rule with the service destination pointing to the Service Gateway.. Setting up a Service Gateway requires creating the Service Gateway resource itself and adding a route table rule pointing traffic destined for the Object Storage service destination to the Service Gateway.

Answer

Assign a public IP address to every compute instance in the private subnet.

Answer

Attach an Internet Gateway to the VCN to route service traffic.

Answer

Configure a NAT Gateway as a next-hop in the subnet route table.

Question 7

Which OCI compute feature allows you to run virtual machines on dedicated physical servers allocated exclusively to your organization?

Accepted Answer

Dedicated Virtual Machine Hosts. Dedicated Virtual Machine Hosts provide physical servers dedicated solely to your tenancy for compliance and isolation requirements.

Answer

OCI Container Instances

Answer

Preemptible Instances

Answer

Standard Flexible VM Shapes

Question 8

Which TWO OCI compute shapes are available when provisioning virtual machines in OCI? (Choose two.)

Accepted Answer

Standard Shapes. OCI offers both Standard virtual machine shapes and Flexible virtual machine shapes where OCPUs and memory can be customized.

Answer

Object Storage Shapes

Answer

Database Shapes

Answer

Network Shapes

Question 9

You are designing an architecture requiring a resilient, fault-tolerant entry point that distributes incoming HTTP/HTTPS traffic across multiple backend compute instances across different availability domains. Which load balancing service should you deploy?

Accepted Answer

Public Load Balancer. A Public Load Balancer provides automated traffic distribution across multiple backend servers and availability domains with a public IP address.

Answer

Local Peering Gateway

Answer

Network Load Balancer

Answer

Dynamic Routing Gateway

Question 10

Which THREE OCI networking components are required to connect an on-premises data center to a VCN via an IPsec VPN? (Choose three.)

Accepted Answer

IPsec Connection. Site-to-Site VPN requires a Dynamic Routing Gateway (DRG), a Customer Premise Equipment (CPE) object, and an IPsec connection.

Answer

Internet Gateway

Answer

Local Peering Gateway
